2SC945-P

Foshan Blue Rocket Elec · Bipolar (BJT) · TO-92

2SC945-P from Foshan Blue Rocket Elec, in a TO-92. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Base input Base of the NPN transistor; the datasheet rates continuous base current IB at 20 mA and emitter-to-base voltage VEBO at 5.0 V.
2 Collector passive Collector of the NPN transistor; the datasheet rates collector-to-base voltage VCBO at 60 V, collector-to-emitter voltage VCEO at 50 V, and continuous collector current IC at 150 mA.
3 E passive Emitter of the NPN transistor, the common reference for the collector and base ratings given in the absolute maximum ratings.
